1) Review the risk factors, diagnostic features and anatomical/morphological classification of cholangiocarcinoma (CC). 2) Describe the typical imaging appearances for intra and extrahepatic cholangiocarcinoma using a multi-modality approach recognizing the distinction between perihilar and distal CC. 3) List findings that are key in determining surgical resectability.
Abstract
Cholangiocarcinoma (CC) is the second most common primary liver tumor worldwide after hepatocellular carcinoma. Incidence and mortality rates for intrahepatic CC are rising. Established risk factors have been determined, but more than 70% of cases are sporadic. The identification of key characteristic features on CT and MRI/MRCP allow for accurate diagnosis and staging. Tumors are classified based on anatomical location into intra and extrahepatic (perihilar and distal) subtypes. This standardizes reporting and helps determine management and planning for either laparoscopy or biopsy. The criteria for surgical resection will be discussed together with options for progressed disease.
